Referring now to the drawings in detail, the numeral 5` designates a rigid tubular casing of a lengthfto form a suitable night stick or billy and a portion at its. rear end 'forms a .hand grip equipped with `a ared end cap 6 removably mounted thereon by set screws 1.' The. front end of thecasing is reducedgto receive a destructible end cap 8 held Vthereon by frictional nt. a Y

Mounted in .the frontend of the casing is a barrelV 9 provided with longitudinal grooves I I. and [circumferential branch grooves I2, the grooves II slidably receiving lugs I3 formedon gas shells I4.j` The gf/isshell'sareV arranged inV end to end relation and are threadedly connected togetheras shownat I4. .The innermost shell is provided in itsinnernend with a Ydetonating cap Itand the remaining shells are provided with detonating` caps` Ifand I'I vin their side walls. The

f detonatingcaps communicate with powder cham#` bers I8 in the vrear ends of the respective shells.

'The powder chambers It'v occupy a comparatively small space rwithin the shells, lthus leaving the remaining portion ofthe shells for the storage of tear gas or similar chemical. Destructibleparti-v tions I9 arearranged'betweenthe gas chambers andthe powderchambers of the shells and each shell has ak substantially conical-.shaped end par.- tition or wall 20of afrigid construction capable of withstanding the force of the exploding powder.

The barrel Qis Vequippedwith spring projected firing pins 2| and ZI' inthewalls of the barrel adapted for striking' the detonating caps I6 and .I'I and theinner end of the barrel is provided with a similar nrin'gpi 22 Vadapted for striking the detonatingfoap'li.

The ybarrel 9 islformed with a 'thickened wall 23 inr its 'ur'perportion provided with a vlongitudinally'extending passage 24 Within which is slidably mounted a. pair 'of rods 25rand 26in side by side relation as shown in Figure 2. The firing pins2 I. and .2 if 'project 'into the passage 2.4 in the path ofA the bevelled front ends of the rods 25land Z respectively, for riding over thev pinsto cause the latterk tol strike jthegdetonating cap `and fire the charge."

A sectionallever" composed :of upper'a'nd lower overlapping se'ctionsZ'and 29 is pivoted at thefrear end of'. the barrely` the. lower section being engageablekwiththe ring pin 22 andthe upper sectionhaving,arearwardly projecting arm 30 *termirriatingxinithefverticaly plane Yof the rear.

end of ,thejrods 25` and 26. y .y f' VA Vshaft' 3i is` rotatably mounted transversely in the casingadjacent the rear end ofthe barrel and is provided with Yan upper spring retracted plungera3`2 slidably mounted transversely in the shaftv and'ra lowerl spring retracted "plunger '.33 similarly mounted in the shaft land angularly with respect tothe axis of the upper plunger. The upper plunger isadapted to strike the 'rods 25jand25 uponl a predet'err'niriedV rotary movementof the shaft andthe lower plunger is likewise adaptedfto strike the arm 30 of the lever 27 for actuating the respective piiring pins. 'e ratchet 3l! is se'cured to the shaft 3l with which a dog l35 is engageable, the dog being pivotednon a hammer in the form of a plate by means of a pin 36.` Also pivoted on the pin 36 is aseconddog 38extending in diverging relation with respect to the dog 35 and yieldably connected to the dog 35 by means of a spring 39 coiled on the pin 36. A pin 4B projects laterally from the plate 50 at the crotch of oppositely extending dogs 35 and 38 to act as a stop in limiting the closing movement of the dogs.

A pin 4| also projects laterally from the dog 35 and is engaged by the notched end 42 of a rod 43 extending longitudinally in the casing and slidably mountedin guides 44.' 'A c'oilspring 45 is mounted' on the rod between the guides for projecting the rod rearwardly and outwardly of the cap 6 to form a handle 46 at the rear end of v the rod. 1

A coil spring 41 engages the ratchet to urge the same in a direction to ree-setl the ` plungersY 32 and 33 when the ratchet is released by the dog 35.

The plate 50 is pivoted on a pin 5| which is.vv

A trigger 55 is pivoted in the casing at 56 andl projects through an opening 51 outwardly thereof. A lever 58 is pivoted intermediate its ends in the casing on a'pin 59, the lower end of the lever being connected to the trigger by'a link 60 through the medium of a pin 6| and slot 62, the upper end of the lever being adapted to engage the dog 38 for actuating the dogs and to rotate vthe plate 50 against the tension of the spring 53. A coil spring 63 is attached to the inner end of the triggerv and is anchored to the pin 59.

The dog is held in engagement with the ratchet by a leaf` spring 64 attached to the plate 50 by means of a block 65 and to the block is also attached one end of safety catch 66 of spring metal having an upwardly extending hookj|1 at its free end engaged over an upstanding arcuate lug or cam 68 projecting radially from the shaft 3| and' a downwardly extending lug 69 also at the free end of the catch 66 adapted to enter a notch 10 formed in an adjacent edge of the dog 35 the angle of the notch enabling the catch 66 to hold the dog 35 out of engagement with the ratchet 34. The catch 66 is released from the dog 35 by the cam 68 upon a rotation of the shaft 3| during its resetting action by the spring 41.

A safety catch designated generally at 'il is, provided andA includes a spring finger 12, shown in detail in Figures l5 and 16, the finger being secured to one end of a pivoted cam 13 and the lfree end of the finger is selectively engaged in notches 14 in the peripheral edge of the'ratchet 34. The arm 13 is pivoted on a pin 15 on which is also mounted a coil spring 16 urging the finger in engaged position and the other end of the arm projects upwardly into the path of the forward movement of the pin 4| for releasing 4the safety catch 1| upon an inward movement of the handle^ 46 and rod 43.

The finger 12 is secured against one side of the arm 13 so that the linger will flex when the ratchet is moved in a direction for the successive firing of the cartridge, but willnot ex upon a tendency of the ratchet to move in an opposite direction and accordingly 'will lock the ratchet against such reverse movement and against the tension of spring 41.

The rear edge of the trigger 55 is formed with a notch 11 adapted for receiving the inner end of a locking rod 18 slidably mounted in the casing'and projecting rearwardly through the cap 6 to provide a handle 19.

A second coil spring is secured to the trigger 55 and operates against the tension of the spring 63 to restrain actuation thereof, the spring 63 being stronger than-the spring 80 to project the trigger from the opening 51 and the two springs cooperating to normally maintain the trigger and lever 58 in the position shown. In the operation of 'the device, and'after the cartridges |4 have been loaded in the barrel, the trigger is held in a safety retracted position by the engagement of the end of the rod 'I8 in the notch '11 of the trigger, the trigger being released by a rearward movement of the handle 19 of the rod 13 tov permit the spring 63 to project the trigger from the side of the handle 5, as shown in Figure 6.

The shaft 3| is normally held in position with the plungers 32 and 33 out of the path of the hammer 56 by the spring 41, as shown in Figure 8, and is locked in such position by the safety catch 1| engaging the notches 14 of the ratchet 31|.

The dog 35 is held out of engagement with the ratchet 34 by the lug 69 engaged in the f notch 'I6 of the dog.

`When it is desired to fire the first cartridge the trigger is released by the handle 19 and the handle 46 is pushed inwardly to cause an engagement of the notched head 32 with the pin 4| which in turn engages the upper end 13 of the catch 1| to pivot the catch and retract the latter from the notches 14.

The rearward .pulling force of the trigger 55 will move the upper end of the lever 58 into engagement with the lower end of the dog 38 which engages the pin 46 on the hammer 56 to rotate the hammer in a clockwise direction, The-initial movement of the hammer will release the lug 69 v from the dog 35 permitting engagement of the dog with the ratchet 34 to actuate the shaft 3| during the continued rotation or cooking of the hammer. This movement of the shaft will bring the plunger 32 into position for striking the rod 25.

After the hammer has been rotated a predeterr mined distance by the trigger, the lever' will ride past the dog 38 to release the hammer and the spring 53 which has been put under tension by the rotation of the hammer will rotate the hammer in an opposite direction to strike' the plunger and re the lirst cartridge.

Release of pressure on the trigger will return the lever 58 rearwardly past the dog 38 into the position shown in Figure 6, whereby the next rearward movement of the trigger will cause the dog 35 to move the ratchet34 another notch and rotate the shaft 3| to bring the plunger 32 into position for striking the second rod 26 to lire the second cartridge.

. The next ring movement of the trigger will move the plunger 33 into position for striking the firing lever 21 to fire the last cartridge. Y
